Process Of Refining Gold

15.05.2018This process is known to purify gold to 99.95%. This method got its name from Francis Bowyer Miller, its inventor. In the Miller process, unrefined gold is first melted. Then, chlorine gas is passed through it. The gas turns other metals and impurities into a solid form, making it easy to separate them from gold.

Process Of Refining Gold

15.05.2018Cupellation is a process that purifies ores by separating gold and silver from base metals and other impurities. The process makes use of a cupel – a high temperature resistant flat bowl. The ore is placed in this cupel which is put in a special furnace. Hot air is then passed through it to remove the impurities.

How gold is made

Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the
